SA'LUIR-A'IOIR. AND COATEIt.

Application filed September 22,1924. Serial No. 739,038.

The invention relates to improvements in saturators and coaters used for making roofing material. It has especial reference to means for adjusting the rolls about which the sheet passes to cause the sheet to run true thereon.

One of the objects of the invention is to provide improved, convenient and effective means for raising and lowering one end of the submerged rolls in saturators to adjust them to positions in proper-relation with the upper rolls thereof.

A more specific object is to .provide means for locking the roll-moving mechanism and the provision of adjacent means for manually supporting the rolls when the mechanism is unlocked, and for raising or lowering one end of the respective rolls to adjust-' ed positions.

means for supporting the lower rolls on the roll-carrying racks, to permit some relative movement of the parts.

Other objects, benefits and advantages will hereinafter appear from a consideration of the following'description when taken in conjunction with the drawing forming a part hereof, wherein:

Fig. 1 shows a fragmentary elevation of one gate of a saturator' and coater, of which there may be a plurality, with the improved.

adjusting device.

Fig. 2 is a transverse section taken on line 2.2 of Fig. 1.

Fig. 3 is a section taken on line 33 of Fig. 2. F Fig. 4 is a section taken on line 4-.4 of

In all the views the same reference characters indicate similar parts.

The invention 'is concerned with means for raising or lowering one end of the bottom rolls of machines of this character, whereby to cause the sheet, which is guided by the upper and lower sets of rolls thru the tank, to run true above and below said rolls and to prevent it from shifting laterally of its true path, thereby to be torn apart.

Insaturators and coaters of the type herein disclosed, there is an elongated, tank 5 to contain the liquid, usually of asphaltic nature, to be applied to the sheet 6, usually a porous felt, to be saturated or coated. There are a series of rolls 7 supported near the top of the tank over which the sheet 'clination of the roll to a small extent. A further object is to provide an improved passes. These rolls are driven at uniform speed, usually by caring 8. The upper rolls have their axes fixed. A series of vertically movable rolls 9 are arranged in vertical planes intermediate adjacent upper rolls.

The lower rolls 9 are arranged to be bodily moved from near the bottom of the tank to any place within or above the tank, to thread the machine when required.

The rolls 9 are each supported by apair of vertically movable racks 1010.. The racks are loosely tied together near their bottom ends by a bar 11 which permits a limited independent movement of the racks with respect to each other. The roller 9 is, preferably, mounted in globular bearing blocks 12, at each end, to permit axial in-' Posts 1313, of which there are a pair for each pair of racks, are located outside of the tank and a're intended to support the racks and the roll carried thereby. To the post 13 a bracket l l' is secured by straps 15. This bracket has a hub 16 thru which the rack 10' is freely slidable. From the hub 16 projects a shaft bearing 17 for the shaft 18. Secured to the shaft is a pinion 19 which is in mesh with the rack 10.

The shaft 18 also carries a pinion 20 fixed thereto, which is in mesh with rack 10. It is apparent that when the shaft is rotated the racks 10-10 will thereby be raised or lowingly bodily raised and lowered. A wheel 21 pinned to the shaft 18 is a convenient means for rotating the shaft. The heretofore described are common in mac ines of thisgeneral type.

' The present invention resides inthe means hereafter to be described, employed for raising and lowering one end of'the lower roll 9, whereby to incline its axis for the purpose of causing'the sheet 6 to run true-over the rolls.

, ered and that the roller 9 will be correspond- 1 arts 26 is fixed to the post 13. The

A cam plate 27 is fixed to the outer arm 22. A similar cam member 28 is rotatable on the shaft 18 by the handle 29.

When the arms 22 are forcibly drawn together they clamp the post 13 and thereby the bracket 14 is firmly secured to the post.

For the purpose of illustration, the arms 22 are not shown forcibly drawn towards each other.

To raise or lower theleft end of the roll 9, the horizontal handle 25 is grasped and the handle 29 is depressed, as shown in Figs. 1 and 2, this causes the cams 27 and 28 to move into position to release the arms 22, whereupon the handle 25 may be depressed to raise the bracket 14, or raised to depress 'the bracket 14 thereby to incline ,the axis of 20,

the roll 9, as indicated by broken lines passing thru the roll. While this is being done, the shaft 18 and pinions 20 are prevented from being rotated by the usual paWls, notshown, but common for the purpose. After adjustment has thus been made, the handle 29 is raised, whereupon the cams 28 and 29 will forcibly draw the arms 22 together to firmly clamp the post '13.

This action will also prevent rotation of the shaft 18 and pinion 20 and the pinion 24 by clamping'the shaft and these parts to the bracket. This supplements the usual means for holding the racks in adjusted position.

Should it be desired to rotate the shaft 18 and the pinions 19 and 20, to raise or lower both racks 1010, this may be done by holding handle25, and moving handle 29 to loosen the cams 27 and 28 and then by turning the hand wheel 21.

The operations heretofore described may convenientlyv and;safely be performed while the machine is in operation and while the sheet is passing through it.

The shaft 18 is mounted rather loosely in its bearings to permit the vertical movement of one end thereof without cramping. The movement to sufficiently adjust one end of the roller 9 is not very great.

Having described my invention what I claim as new and desire to secure by Letters Patent, is a 1. In a machine for saturating or coating a moving sheet, a saturator having a container for the liquid to be applied; a guide "roll for thesheet located near the top of the container; a guide roll -for the sheet near the bottom of said container; raising and lowering means forbodily raising and lowering said bottom roll; posts, one on each side of said container for supporting said raising and lowering means; a rack fixed to one of said posts in combination with a pinion in mesh with said rack and having a handle extending therefrom whereby to raise and to lower one end only of said lower roll supplemental to the first named raising and lowering means, and means to clamp said pinion to prevent its rotation and movable to permit its rotation. 2. In a machine for saturating and coat ing a moving sheet, a saturator having a container for the liquid t be applied; a rotatable guide roll supported near the top of the container; a vertically movable sheetguiding roll below the upper roll; rack and pinion means, to bodily raise and lower said lower roll and another rack and pinion means near one end of. said roll to'raise and lower one end only of said roll.

3. In a machine for saturating or coating a moving sheet, a saturator having a. tank to contain the liquid to be applied to the sheet; a driven roll supported near' the top of the tank; a vertically movable sheet-guiding roll normally below the upper roll in combination with a means to bodily raise or lower said lower roll; supplemental means near one end of said roll to raise and lower one end only of the, latter roll and a means to lock both said raising and lowering means to support the lower roll in adjusted position.

4. In a machine for saturating or coating a moving sheet, a saturator having a tank to contain the liquid to be applied to the sheet;

v a rotatable roll supported nearthe top of the tank, to guide the sheet; a vertically movable, rotatable roll in said tank-normally below the upper roll; a pair of rack bars upon which'said lower roll is supported and by which it may be bodily raised and lowered; a shaft carrying a pair of pinions in mesh with the respective racks rotatable to raise and lower said roll supporting racks in combination with a fixed rack; another pinion rotatable on' said shaft and in mesh with the fixed rack, rotatable independently of saidshaft to move one end only of said lower roll, and means to prevent movement of both said roll moving means.

In testimony whereof I hereunto subscribed my name.
